While full thickness rotator cuff tears are very common, let’s back up and start with the basics about these 4 little muscles.  The rotator cuff plays a key role in the proper function of the shoulder.  The rotator cuff can be a source of pain for many many reasons.  Pain can be due to inflammation, degeneration or tears of the rotator cuff.  Tears of the rotator cuff come in all shapes and sizes.  Fraying of the rotator cuff tendon surface, partial thickness tears, and full thickness rotator cuff tears are all quite common.

How do Orthopedists figure out which one you have and how does that effect our treatment strategies?

Rotator Cuff Tears:

Before we delve briefly into whether or not you have a full thickness rotator cuff tear (complete tear),you need to know what the rotator cuff is. 

Full Thickness Rotator Cuff Tear

Full Thickness Rotator Cuff Tear

The rotator cuff is a series of four muscles, which combine at the shoulder to form a cuff of tissue completely surrounding the top of the arm bone or humerus.

Rotator cuff tears can be described in many different ways.

  • There are traumatic tears (accident or a fall), acute tears (just happened)
  • Chronic tears (present for a while, you just didn’t know it)
  • Degenerative tears ( your tendon just wore out).

Rotator cuff tears can also be described as being partial, or full thickness.  With partial thickness rotator cuff tears  only part of the tendon has torn off the bone.  With full thickness tears the entire tendon has separated or torn from the bone.  Click here to learn about partial thickness tears.  

Can you tell if you have a full thickness rotator cuff tear?

After a significant trauma such as a fall or a car accident, your rotator cuff tendon can literally pull right off the bone.  We call that an acute, traumatic full thickness rotator cuff tear.  On the other hand, I see many patients in the office who do not recall any significant injury, but their exam and MRI demonstrate that they have a full thickness tear — why is that? The risk of developing a rotator cuff tear increases with age because our tendons begins to gradually wear, lose its blood supply and its resilience. In that situation, even routine daily activities like gardening or working around the house  increase the potential for wear, degeneration, and tearing.

 

 

 

Whether your tear is chronic, attritional (wear and tear) or acute and traumatic (fall or injury)  is a VERY important element of the decision making process in how we treat full thickness rotator cuff tears.   Treatment decisions are based not only on the type of tear you have, but whether or not other treatments have failed, and how poor your quality of life is.

Full thickness rotator cuff tears

Rotator cuff tears come in all shapes and sizes.  Many patients have full thickness rotator cuff tears and do not even know it.  As a matter of fact, by the time you reach 65 you have more than a 50% chance of having an degenerative rotator cuff tear because of wear and tear.   No need to panic…

Shoulder Pain:  

Does the amount of pain you are having correlate with the size or thickness of your rotator cuff tear?

The size of the tear usually doesn’t correlate with the pain you are experiencing.  Many patients mistakenly believe that they must have a large full thickness rotator cuff tear because they are in severe pain … usually the opposite is true.   Many patients with severe shoulder pain have very small full thickness rotator cuff tears,  partial thickness rotator cuff tears, or no tear at all.   Yet some patients with mild shoulder pain have massive rotator cuff tears.  Bottom line… the size of your tear will not correlate with the amount of pain you are experiencing.  Many patients with tendonitis or bursitis have more pain than patients with rotator cuff tears. Many patients with tendinosis, small tears, large tears or just bursitis usually have very severe pain at night.   Night pain can be very disruptive, aggravating and demoralizing.  Night pain is frequently the reason many patients cite why they opted for surgery to repair of a full thickness rotator cuff tear.

Weakness:

The rotator cuff muscles control the motion and the overall strength of the shoulder.   Small tears do not produce shoulder weakness, however,  large or massive tears can produce very significant shoulder weakness.

Patients with large rotator cuff tears complain of weakness and the inability to place the arm in certain positions.  They have difficulty taking milk out of the refrigerator and may need to support their injured arm with their other arm when attempting to lift something.

Loss of motion:

Most rotator cuff conditions which produce pain will lead to loss of motion.  Many patients with rotator cuff related pain will complain of difficulty with hair care, putting on a bra or belt, and weakness when trying to lift the arm away from the side. Sometimes patients with full thickness tears will have significant loss of motion, and sometimes patients with large rotator cuff tears will have normal motion.  That means that loss of motion, in general, is a poor predictor in and of itself of the presence of a full thickness rotator cuff tear.  

A thorough physical examination by a Sports Medicine trained specialist is usually necessary to determine whether a rotator cuff tear is present.

Ultimately an MRI or an ultrasound may be necessary to confirm the presence and size of a rotator cuff tear and determine if it is partial thickness or a full thickness rotator cuff tear.

Whether you have a full thickness tear or a partial thickness tear, your pain may be so severe that your quality of life if very poor. You’re not sleeping well and you have very limited use of your arm.  Not all tears require surgery… but some do.  Click on the the Book an Appointment button below and let’s discuss what treatment option best suits your needs.
